Uniform Rectilinear Gun

ABSTRACT

This invention is a precision weapon that utilises solely as a projectile, a precision-ball made out of a suitable material namely solid C260 brass. It employs a smoothbore precision-barrel with a metal toothed rack/rail affixed along the northern hemisphere of the muzzle of the barrel that effectively converts some of the forward motion of the ball into rotational motion so that the ball is mechanically forced to rotate upwards/backwards at very high speed that can run into millions of rotations per minute, vastly improving it&#39;s ballistic coefficient and downrange accuracy. The weapon can be produced in a variety of existing types of firearms such as bolt-action, falling-block or semi-automatic, and can be chambered for a variety of calibers. A 5.5625 mm caliber bolt-action rimfire weapon for instance will provide a user with a weapon ideal for hunting small-game or for target shooting purposes.

BACKGROUND OF THE INVENTION

The field to which the invention pertains is small-arms, firearms andairguns in particular and projectile-discarding weapons on a muchbroader scale. The quest for a projectile-discharging weapon with aneven flatter trajectory is ongoing and relentless. Most projectilesemployed in the industry are usually pointed for a better ballisticcoefficient and yet are expected to dissipate as much kinetic energy aspossible once they meet a target. This entails distinct and complexforms that are usually expensive to produce. In addition, the only wayto achieve very flat trajectories utilising such projectiles seems to bevia elevated muzzle velocities.

BRIEF SUMMARY OF THE INVENTION

This invention is a precision weapon that utilises solely as aprojectile, a precision-ball made out of solid copper or C260 brass orother suitable material or a combination of these materials. A balldischarged from the weapon is mechanically forced to rotateupwards/backwards at very high speeds that can run into millions ofrotations per minute, vastly improving it's ballistic coefficient anddownrange accuracy. In addition, the ball's trajectory is expected to bealmost flat for a distance that can be expressed as a proportion of it'smuzzle velocity. This means that a user will not need to factor inprojectile trajectory-drop for specific ranges. Wind drift should alsobe reduced when compared to other weapons that discharge pointed andelongated projectiles since gyroscopically spun projectiles of thistype, that spin clockwise or anticlockwise around their longitudinalaxis, are more likely to drift to the left or the right as they traveltowards an intended target. The precision-ball is a straightforward,economical and uniform projectile that, due to a very high rate ofupward/backward spin, will remain true in flight, maintain a relativelyflat trajectory even at relatively low velocities and can achieve idealkinetic energy transfer once it impacts a target, without overpenetrating. The backspinning nature of the ball combined with a veryhigh rate of rotations per second means that the ball is unlikely toricochet off a hard surface and is compelled to move downwards towardsthe ground upon impact, making it a safe alternative.

DETAILED DESCRIPTION OF THE INVENTION

A gun comprising a source of propulsion in the form of a rimfire orcentrefire cartridge or a compressed-air source or other (7) andutilising solely as a projectile, a precision-ball (1) made of asuitable material such as C260 brass, that also employs a stainlesssteel or other precision-barrel (2) with a tungsten carbide coated orother precision smoothbore (3), also employing a metal toothed rack/rail(4) of specific dimensions and perforated in specific places, that isslotted through along the northern hemisphere of the muzzle of thebarrel and is non-permanently affixed via steel holding pins (5), sothat only the teeth penetrate a portion of the northern hemisphere ofthe muzzle of the bore, a specific distance, and engage and indent (8)the northern leading edge/circumference of the ball as it progresses toexit the barrel of the gun, effectively transforming the leadingedge/circumference of the virgin ball into a cog wheel. The length ofthe toothed rack/rail is equal to the caliber of the weapon multipliedby 3.14159, however any specifications or dimensions relating to thetoothed rack/rail, it's positioning and the method of affixing it to thebarrel are subject to change.

Alternatively, the toothed rack/rail can also be directly cut into thebore of the barrel as part of the barrel manufacturing process.

The virgin ball accelerates through the precision smoothbore barreluntil it encounters the first of a series of triangular teeth of therack/rail, penetrating the northern hemisphere of the muzzle of the boreand is mechanically forced to rotate upwards/backwards as eachprogressive tooth engages and indents it's northern leading edge. Theball leaves the barrel of the gun under the influence of the toothedrack/rail that presses it downwards against the southern hemisphere ofthe muzzle crown and locks it so that, when viewed from the front, itcannot rotate either clockwise or anticlockwise.
